LAHORE, Pakistan (CNN) -- A Pakistan military helicopter that was escorting Pakistan's president, Gen. Pervez Musharraf, crashed in Pakistan-held Kashmir Monday, killing at least four people, according to Pakistan Army and intelligence sources.

Crowds gather round the wreckage of the crashed helicopter.

Musharraf was not on board the helicopter, and he arrived safely at his destination, the officials said. Along with the four security officers who died, the presidential press secretary, Rashid Qureshi, and several other people were seriously injured, the officials said.

Musharraf was on his way to visit an area damaged by the deadly October 8, 2005, earthquake, on its second anniversary.

The helicopter, an Army MI 17, crashed in Neelam Valley, in the northern section of Kashmir, the officials said.

It comes two days after Musharraf won an election boycotted by much of the opposition, and while the Supreme Court considers the eligibility of his bid while still army chief.
